Specification of Letters Patent.

Patented March 20,, 1906.

Application filed March 8, 1905. Serial No. 249,026.

. To all whom, it may concern:

Be it known that I, GEORGE L. RIOKS, a citizen of the United States, residing at Yuma, in the county of Yuma, Territor of Arizona, have invented certain new an useful Improvements in Insulators; and I do hereby.

declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to insulators for electric conductors, and has for its object to provide a device of this nature which will be simple and cheap. and which will be. so arranged that wires will be quickly and securely ongaged therewith.

Other objects-and advantages will be apparent from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure l is an elevation of the present invention, showing a wire engaged therewith. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a perspective view of the two members separated and showing the mutually-engaging faces thereof. i

Referring nowto the drawings, the present invention comprises a base member 5 and a cap member 6, which are circular in form, the upper face 7 of the base member being convexed. Formed on the upper face of the base member and extending thereacross there is a projection 8, this side of the center of t e base member. The base member has a central vertical passage 10 formed therethrough, and formed upon the upper surface of this member between its passage and the projection 8 there is a second projection 9, which terminates short of.

the edges of the member. The projection 8 has a vertical wall 11, which extends upwardly from the face 7 of the member 5, and between its ends this wall is curvedinwardly, as shown at 12, the projection 9 being also curved to conform to the curve of the wall 11.

The cap member 6 has a concaved under surface ,13, which is cut away, shown at 14, toreceive the projections 8 and 9, and the wall 15 of its'uncut-away portion is pocketed to receive the projection 9, as shown at 15,

and beyond the pocket lies spaced from the rojection lying at one portions of the wall 11, which project beyond the projection 9 to form wire-receiving pas" sages commumcatmg with the space between the projections, it being understood that the cap member is disposed upon the base mem her. The cap member 6 is provided with a central passage 16, which ah'ncs with the pa sage 10 for the reception of a screw or other attaching device 17.

In use the two members are engaged with the attacl'iing device and are separated sufficiently to permit of the passage of a wire into the wire-receiving passage, after which the fastening device is operated to hold the two members in close relation to prevent disengagement of the wire therefrom.

What is claimed ing a base member aving a central passage and having a convex surface, said member having a projection formed upon its convex surface at one side thereof and extending to the edges ofthe member, said projection having a Wall extending at an angle to the surface of the member, said member having a second projection between its first projection and its central passage, the two projections lying in spaced relation, ,the second projection terminating short of the edges of the member, and

a cap member having a concave surface for the reception of the convex surface of the base member thereagainst, said concave surface of the cap member being cut away to receive the projections of the base member, the wall of the cut-away portion of the cap member lying in spaced relation. to the portions of the wall of the projection of the base member which extend beyond the second projection of said member to form a wire-receiving passage communicating with the space between the projections of the base member, said cap member having a passage alining with that of the base member, and an attaching device engaged in the alining passages.

2. In an insulator, the combination witha base member having spaced proections upon its upper surface following the same general direction, one of said projections extending oppositely beyond the other, of a cap member disposed upon the base member and having a cutaway portion to receive its projections, the wall of the uncut-away portion of 1. A device of the class described compristhe cap member lying in spaced relation to In testimony whereof I afiix my signature the longer projectlon to form Wire-receiving in presence of two witnesses.
